Cam swap

Cam swap
Is it true that ls1 engines have some type of tab that will hold the lifter in place that you could pull the pushrods, rotate the engine, getting all the lifters up, and pull out the cam without removing the intake. I heard this the other day, and I though it was unlikely. If its true I will say that chevy is got some kickass engineering.

Sorry for the newb question. I just got so excited when I heard that I didn't take the time to research it. That's pretty impressive. I've been working on fords for years, but I'm new to the ls1 deal. I'm am more and more impressed with these cars everyday with what I learn. So with 58k I shouldn't depend on the cups to hold the lifters up then?

pen magents work good, but try to find the ones with the 3/16" magnetic tip...the larger ones (3/8"?) are hard to get back out of the lifter hold-down trays. Took me 1/2 hour to get one of those bigger ones wiggled back out...
Take my word for it.

My vote goes to 5/16" dowel rods. Cheaper than pen magnets and they (the magnets) do not have a 100% success rate either. Searching should give you all the info you need on this too.However, you should ahve at least one pen magnet style magnet, I am told, to quickly and easily remove the keepers/locks once the spring is compressed.
